Essential tremor treatment with acupuncture

A tremor is an involuntary rhythmic muscle contraction involving movements of one or more parts of the body. It may be intermittent or constant. It is a common movement disorder that most often affects the hands but can also occur in the arms, head, vocal cords, torso, and legs. Most types of tremor have no known cause, although there are some forms that appear to be inherited and run in families. Tremor can occur on its own or be a symptom associated with some neurological disorders, including multiple sclerosis, stroke, traumatic brain injury, Parkinson's disease, the use of certain medicines, anxiety or panic attack.
Essential tremor is a nervous system (neurological) disorder that causes involuntary and rhythmic shaking. It can affect almost any part of your body, but the trembling occurs most often in the hands.

Essential tremor is usually not a dangerous condition, but it typically worsens over time and can be severe in some people. Other conditions don't cause essential tremor, although essential tremor is sometimes confused with Parkinson's disease.

Essential tremor can occur at any age but is most common in people age 40 and older.

Essential tremor vs. Parkinson's disease

Timing of tremors is different. Essential tremor of the hands usually occurs when you use the hands. Tremors from Parkinson's disease are most prominent when the hands are resting.

Associated conditions. Essential tremor generally doesn't cause other health problems, but Parkinson's disease is associated with slow movement and stiffness.

Acupuncture is used for essential Essential tremors and there were case reports that essential tremors are improved with acupuncture treatments.
